High accuracy is accomplished by marrying a high performance ASIC to a very stable polysilicon thin film pressure sensor. The sensor is electron-beam welded to a pressure fitting of stainless steel, providing high overpressure capability and outstanding durability against shock and vibration. Transducer circuitry is held securely within an internal cage and housed in a reinforced nylon enclosure. Accurate and reliable performance in a compact, durable package ±1 percent total error band accuracy high EMI/RFI rating high temperature capability.
